Distribution and collection site descriptions.

Known from two or possibly three sites in Los Angeles County and two sites in Orange County in Southern California. The Los Angeles County sites include the type locality in South Fork Elsmere Canyon, San Gabriel Mountains and East Fork Arroyo Sequit, Santa Monica Mountains (Fig. 34). In Orange County, Trabuco Canyon and Silverado Canyon in the Santa Ana Mountains are the known sites.

Material examined. Orange Co., 6 collections by K.W. Stewart and E.F. Drake 6-IV-2004 to 22-II-2006, same locality vicinity, Silverado Creek, Silverado Canyon, at gravel low water crossing 161m above Forest Boundary Gate, 33 ° 44 ’ 55 ” N 117 ° 34 ’ 58 ” W, 117♂, 19♀, 3 pairs in-copula, 4 larvae, 1 exuvium. Deposited in B.P. Stark collection, Mississippi College, Clinton MS.

Characters of mature larvae. (some measurements and counts, as done for C. ephemera, were not made because of the few larvae available for study). Color, pigmentation, general body and cercal setation (Fig. 21), and mouthparts typical of genus. Body length 7- 8 mm. Head capsule width (1♀ larva) 0.75 mm. Antennal segments 60-64, each with very short apical circlet of hairs or sensillae. Lacinia triangulate and palmate, with 2 rounded-tipped apical teeth, 8-10 dorsal and ventral rows of long, sharp spines (Fig. 25), and a scalloped palm surface. Right mandibular molar cup outer margin, in side view, appears as a row of blunt-tipped, stalked teeth (Fig. 26) that are actually the outer edges of 10-12 stalked ridges extending well onto the inner cup surface (Fig. 27). Left mandible molar cup with comb-like outer teeth (Fig. 28; cup of the 1 larva sacrificed for SEM was well worn, in poor condition). Mesosternum with a double stem of its Y-ridge. Foreleg femoral and tibial surface with sparse hairs and with variable number of fine fringe hairs; apex of tibia with 2 heavy apical spines (Fig. 22). Tarsal segments 1, 2 with double vental row of short thick setae. Abdominal terga with long, fine appressed surface clothing hairs; terga 7-9 without thick setae (Fig. 29), especially laterally, as are present in C. ephemera (Figs. 16-18). Terga 7-8 with 2 diverging basal, sublateral rows of short, thick sensillae (Figs. 30-31), not present in C. ephemera . Cercal segments 20-22, each with apical circlet of more than 15 stiff hairs, except few apical and preapical cercomeres (Fig. 16); basal segments with some hairs longer than the following segment (Fig. 32).
